My hubby and I are ttc and this cycle has been a doozy. I am currently tracking my cycle counting days and trying to observe certain signs. I believe my fertile window was between the 25 thru the 29 of April. I spotted a little one day on May 12th I am currently 4 days late. Is it possible to have impantation bleeding is that late? So far I have some symptoms sore bb's for 2 weeks, cramping, frequent urination, always tired because I can't sleep at night because I'm getting up constantly to pee or I can't get comfortable. I was suppose to start my period May 14th is it too soon if that was implantation bleeding? What are my odds?
